Where the gameland trail emerges from the woods at the covered brdige
@Margaret Curtin and I found this moss growing intermingled with Sphagnum cuspidatum in a bog. A search of herbarium records shows this species to be a new Sphagnum for Dukes County, MA.
Mixed in with mats of Andreaea rothii (and a few other spp) on the edges of seepy conglomerate bedrock on a mountaintop.
